I know they contribute little to the bioload, but my Chi already has an adult dwarf gourami and four adult cardinal tetras plus an apple snail. It currently has three ghost/glass shrimp but they are incredibly tough to see amongst the Java Fern and Amazon swords, so I probably want to replace my invisible pets with something a little more interesting. What are your thoughts?

And before the inevitable "omg that's too many fish" person comes along 1) I do a gallon water change weekly as I do a 20% on my two saltwater tanks as well (a Heavily modded 29 gallon Biocube with amazing DIY Cree LEDs and refugium that is my coral tank and another 5 gallon Chi that has dwarf seahorses). And 2) everything is fully adult, fat and Happy (my dwarf gourami is basically Jabba the hut as the little piggy only swims quickly when I try to spread the food around the tank and he tries to eat EVERYTHING before the perfectly healthy cardinals can get to it).
